Description:
  • 4x outputs (H bridge) with PWM control and 24 to 48 VDC ±25% supply
  • 6 A nominal current (10 A max current)
  • 15 Hz to 50 kHz frequency, 16-bit
  • PWM resolution, 15-bit, + sign, minimum 10 ns
  • Configurable dither
  • 4x 4 inputs 24V, can be configured as ABR
  • Sink connection
  • 1-wire connections

The PWM motor bridge module is used to control 4 DC motors with a nominal voltage of 24 to 48 VDC ±25% at a nominal current up to 6 A. The module can be reconfigured and used in current controller mode for controlling inductive loads. The module is also equipped with 16 digital inputs, which can be used as incremental counters. The 4 motors are controlled with a full-bridge (H-bridge). This enables the motors to be moved in both directions.
